Your experts model in the spreadsheet grid they already know. Developers expose those models to pipelines, apps, and AI agents via clean APIs — no translation, no rewrite. Change once; every downstream system updates instantly. End users get governed, trustworthy solutions faster.
Born from a platform acquired by Goldman Sachs. Trusted by modeling teams at major financial institutions.
Now AI-Native via MCP Server — your models are instantly discoverable and queryable by agents.
We won’t replace Excel for everything. But for the financial models that drive enterprise decisions — the ones that need governance, transparency, programmatic access, and the ability to evolve without breaking — ClearFactr does things Excel physically cannot do.
And the people who consume those models — the end users across the entire enterprise — get solutions that are faster, more reliable, and built on data they can trust.

Lock down all the business logic that controls a chosen cell, with one click. The inputs remain editable.
Instead of =B3*(1+$A$7), you see “Revenue × (1 + Growth Rate).” ClearFactr deterministically renders every formula in natural language using your own row and column names. The model documents itself. Change it, and the documentation updates instantly. No comments to maintain. No formula glossary to build.
In Excel, five scenarios means five times the complexity. In ClearFactr, scenarios are thin overlays on one compact base model. Change inputs, or formulas (!), but in the same model. It never grows. End users get every scenario instantly — no one has to rebuild the spreadsheet.
Push inputs in, get computed outputs back, nothing is saved. The model isn’t modified. It’s a pure, stateless computation. Multiple processes call the same model concurrently with zero conflicts. That's what makes it infrastructure — not just a tool someone opens.
Change a formula, add a row, adjust an assumption — every scenario, every API call, every agentic workflow picks up the change immediately. No export. No code generation. No deployment. No reconciliation. The model is the application logic. End users get updates the same day instead of waiting weeks.
Specify a period type — monthly, quarterly, yearly, daily — and ClearFactr auto-generates semantically time-aware columns. No manual date labeling. No date consistency bugs across tabs. Time-series forecasting is a first-class structural concept.
CFSQL connects models directly to Databricks and other cloud data warehouses. Your model pulls live data — no CSV exports, no stale snapshots, no broken data pipelines.
ClearFactr is a Databricks Technology Partner.
The spreadsheet model IS the computation engine. Connect it to your systems via REST APIs, embed it in your UI with the Client-Side API, or let AI agents invoke it via MCP. Your code gets simpler. Your time-to-market collapses.
Stop reverse-engineering business logic from SMEs. Build directly on their models instead.
Your end users get:
Richer UIs, faster delivery, and a single source of truth they can trust.
Profit opportunities are front-loaded. The team that delivers first wins. ClearFactr compresses delivery from quarters to weeks, with governance, audit trails, and enterprise security underneath.
SMEs stay productive in a grid they know. Compliance gets control they’ve never had.
Your end users get:
Solutions sooner, with confidence the numbers are right and versions are current.
Self-documenting formulas.
Immutable version history.
Compute-chain permissioning.
Audit trails built in, not bolted on.
Engagement monitoring and facilitation.
ClearFactr reduces Model Risk and EUC risk structurally, not operationally. This isn’t a monitoring tool. It’s infrastructure that makes models inherently governable.
Your end users get:
One governed answer. Slashed spreadsheet and operational risk. Peace of mind.
Build models in a familiar grid with comprehension tools no other spreadsheet offers. Self-documenting formulas, scenario overlays, Monte Carlo, version control, engagement management.
Read, write, and compute against any model programmatically. Stateless. Conflict-free. Real-time. Use models as deterministic calculation endpoints inside any workflow.
Embed a live, interactive ClearFactr model directly inside your own browser application. Full bi-directional messaging between your app and the model. Your end users interact with a polished, purpose-built interface — they never need to know there’s a spreadsheet underneath.
Inputs in, outputs out — stateless, conflict-free, concurrent. Self-documenting formulas let agents reason about the logic. This wasn’t a bolt-on; the architecture was built for it years before MCP existed.

Modeling often demands trade-offs: scale vs. transparency, speed vs. control. ClearFactr eliminates the need to choose, delivering all four in one seamless platform.

This is powerful. This is real financial modeling!

A major financial institution used ClearFactr to handle complex financial logic “from code” — the application’s entire computation layer lived inside ClearFactr models, called via API. The team that built it included senior developers who validated ClearFactr by seeing the full-stack picture: Web App + Server API + Client API working as a coherent system.

A 4,670% ROI.
That’s what Claude Cowork's model showed for enterprise deployment at scale.
Even at 25% applicability, the return is four digits.
Every unmanaged spreadsheet is a liability — version risk, trapped data, opaque logic, zero auditability. The people who depend on those spreadsheets — end users hunting for the right version, worrying the numbers don't match across systems — bear that cost every day. ClearFactr transforms the same business logic into Software Capital: governed, versioned, API-accessible, AI-ready, and self-documenting. The formulas don't change. The risk does. The end-user experience transforms from frustration to confidence.
AI-powered development tools are bringing software capabilities to more people than ever. The time for this transformation has never been better. Organizations that move now build a compounding advantage. Those that wait build a compounding liability.
